Abstract

A random weight item transaction system include a scale with label RFID tag functionality, service person RFID tag functionality and customer RFID tag functionality. A slicer in proximity to the scale may include service person and bulk food product RFID functionalities. The scale may make weigh transaction data available to a computerized checkout system via a communications link or via writing the information to the label RFID tag.

Claims

1-32. -32. (canceled)

33. A label printing mechanism for handling labels with associated RFID tags, the mechanism comprising:

a housing;

a label supply location within the housing;

a print head located within the housing along a label path for printing indicia on labels passing thereby;

a label RF unit for reading and/or writing label RFID tags on labels, the label RF unit positioned downstream of the print head along the label path so as to read and/or write label RFID tags after printing on the labels carrying the label RFID tags has been effected by the print head; and

a controller associated with the print head and the label RF unit for operation thereof.

34. The label printing mechanism of claim 33 wherein

a peel bar is located for separating labels from label stock,

the label RF unit is located downstream of the label peel bar so as to read and/or write label RFID tags on labels that have been removed from label stock.

35. The label printing mechanism of claim 34 wherein a RFID tag feed unit is located between the peel bar and the label RF unit for applying label RFID tags to labels.

36. A food product scale incorporating the label printing mechanism of claim 34, further comprising:

a weighing station for receiving an item to be weighed;

the controller operable to establish a price for a weighed item based in part upon a weight indicative signal produced by the weighing station.

37. The food product scale of claim 36 wherein

in connection with weighing and pricing an item the scale is adapted to output a label with an associated label RFID tag having an identification number, the label RF unit detects the identification number stored in the associated label RFID tag or writes the identification number to the associated label RFID tag.

38. A package wrapping machine including the label printing mechanism of claim 34.

39. The label printing mechanism of claim 33 wherein

the housing around the label RF unit includes RF shielding.

40. A label printing mechanism for handling labels with associated RFID tags, the mechanism comprising:

a housing;

a label supply location within the housing;

a print head located within the housing along a label path for printing indicia on labels passing thereby;

a label RF unit for reading and/or writing label RFID tags on labels; and

a controller associated with the print head and the label RF unit for operation thereof, wherein during a label output process the controller is operable to;

control the label RF unit to identify whether a given label includes a non-function label RFID tag and, if so, to control the print head to effect printing of a void indication on the given label.

41. The label printing mechanism of claim 40 wherein

the label printing mechanism includes a user display screen, the controller connected for controlling information display by the user display screen;

if the controller identifies that the given label includes a non-functioning label RFID tag, the controller further operates to cause the user display screen to display a bad label message.

42. A food product scale incorporating the label printing mechanism of claim 40, further comprising:

a weighing station for receiving an item to be weighed;

the controller operable to establish a price for a weighed item based in part upon a weight indicative signal produced by the weighing station.
